Gordon Korman writes a lot of books for preteens and high schoolers. I don't like any of his newer books, but his books written in the 80s and 90s are quite funny and good. I recommend: No More Dead Dogs, Don't Care High, Semester in the Life of a Garbage Bag, Losing Joe's Place, Who is Bugs Potter? and my favorite, I Want to Go Home.
A few of them I laughed out loud several times at. Light reads that are entertaining, if nothing else.
